adam1973 1 Posted October 1, 2007 1; After seeing some large capacity 7.2v batteies on the bay, what kind of charger would you use? Any recommendations? These are the type I am thinking about; http://cgi.ebay.co.uk/7-2V-6000mAh-RC-CAR-...1QQcmdZViewItem 2; After fitting a TEU 101bk ESC to my M04KL Beetle, and completing the set procedure, and after a 5min test drive my living room, all it seems to do is bleep and light blink. According to the set up manual, it states that there is no signal from the transmitter (it's an Acoms techniplus), but..... the transmitter has new batteries, and is working propery. Thanks, Adam.

ryanbored 3 Posted October 1, 2007 If i Turn off the tranny when using this speed controller then i get them same symptoms that you've encontered. So: 1 make usre your crystals are seated properly in the tranny and receiver 2 make sure the battery flap on the back of your tranny is on ok, and you are getting power 3 make sure no-one else is running your frequency nearby It seems by your post that had it working, so something must have come loose. Now i'm gussing its to do with the transmitter end as cos if the receiver was getting no power then it wouldn't bleep or flash As far as chargers go, you don't really need a specialist one, just a peak charge will do it. For simplicity something by GWS or ripmax will do the trick. Spend about 30 ish and make sure it's peak detect. I'll add you some links later if i remember Ryan Share this post Link to post Share on other sites
adam1973 1 Posted October 1, 2007 Thanks Ryan, I checked all the conections, several times infact. Even after unplugging and reconnecting, still the same happenings. Share this post Link to post Share on other sites
Backlash 481 Posted October 5, 2007 Adam To me, it looks as though that battery you are looking at, is made from 24 "AA" size cells, not the sub "c" cell that is used for RC cars. "AA" cells generally do not have the ability to be charged at high currents, nor are they designed to cope with the high discharge currents associated with RC cars, especially those with twin motors. I would stear clear of these. If you want long runtimes, try some of the 4200mAhr+ 7.2 volt packs that are designed for RC use. Now for your car.... and just to add to what Ryan has said. OK, does anything work in the car at all?? Does the car steer? Personally, the first thing I would do is Test your Transmitter and the receiver in your car. To do this, disconnect and remove the ESC (Teu101BK) from the car all together. Fit 4 new AA batteries to the battery holder & switch that came with your radio, and plug that into the battery port on the receiver. I would also connect the second servo to the Channel 2 port on the receiver. Then turn on the transmitter, and then the 4 AA batteries in the car, and use the transmitter to controll the car. If you find that the car steers, and the second servo moves when you move the throttle, then your radio is OK. Please let me know what happens Cheers Share this post Link to post Share on other sites

blakeatron 16 Posted November 15, 2007 I believe that if you have only driven it in your house then there could be problems coming from your house - insulation, tv's, electrical appliances can all cause 'static' that will interfere with signals - especially on 27mhz Share this post Link to post Share on other sites
